Fish - scale Expansion Sleeve Anchor YZP: This anchor features a unique fish - scale pattern design on its body, which increases the friction and grip when inserted into a drilled hole. Typically made from metal materials such as carbon steel, which is often galvanized or zinc - plated to enhance its corrosion resistance. The "M8" marking on it indicates its standard size specification. It is a reliable and sturdy fastener, widely used in various fields. In construction, it can be used to secure wooden beams, metal brackets to concrete or brick walls. For furniture installation, it helps in firmly attaching shelves, cabinets to walls. In industrial settings, it is applied to mount machinery and equipment to the factory floor or walls, ensuring stability and safety.

Instructions for Use：

Fish - scale Expansion Sleeve Anchor YZP is used to anchor objects to various base materials like concrete, brick, or wood. First, use a drill bit that matches the diameter of the anchor to drill a hole in the base material. The depth of the hole should be slightly longer than the length of the anchor. After that, clean the hole to remove any debris. Insert the Fish - scale Expansion Sleeve Anchor YZP into the hole. When a screw or bolt is inserted through the two holes on the anchor and tightened, the fish - scale - like structure of the sleeve expands outward, tightly gripping the inner wall of the hole and creating a secure anchor point for the attached object.
